Koin Compiler 1.0 is here. 🎉 Live from @KotlinConf.

DI safety moves from runtime to compile time: broken dependencies caught at build, full-graph checks across multi-module projects.

Kotlin 2.3.20 · Koin 4.2.1

NEW POST

Will there be source code in the future? To wrestle with this, we have to understand what code is. Unmesh Joshi sees code as having two distinct but intertwined purposes: instructions to a machine and a conceptual model of the problem domain.

Happy to host two sessions at AI Heroes, June 29 🇮🇹

🛠️ 9:30 Workshop: ViewModel perf in the AI era
🎯 14:50 Talk: The Next Software Crisis Won't Be About Writing Code

When code is nearly free, architecture is the only thing that survives.

@canerkaseler This is why we have several DI mapping concepts skills, and Kotzilla MCP Server to help drive on the right track. Happy to share if you want to test

[Arnaud Giuliani @arnogiu]

AI writes the code. But does it mean anything?
LLMs predict. They don't understand, it's semantically hollow.
DDD, Clean Architecture, Evolutionary Architecture are not best practices anymore. It's minimum viable foundation.
